It turns out that the InterruptThrottleRate module parameter was only having the effect of locking the ITR at the starting ITR value. This was because the values stored in rx_itr_setting and tx_itr_setting were being ignored when configuring the initial itr_val of the q_vector. Signed-off-by:

We were incorrectly checking the entire frag_off field when we only wanted the fragment offset. As a result we were not pulling in TCP headers when the DNF flag was set. To correct that we will now check for frag off using the IP_OFFSET mask. Signed-off-by:

During shutdown it's possible for __dev_close() (which holds rtnl_lock) to clear the __LINK_STATE_START bit, and for ixgbe to then read that bit (without holding rtnl_lock), and then not fail to free irqs, etc. The result is a crash like this: ------------[ cut here ]------------ kernel BUG at drivers/pci/msi.c:313! invalid opcode: 0000 [#1] SMP last sysfs file: /sys/devices/system/cpu/cpu3/cache/index2/shared_cpu_map CPU 1 Pid: 5910, comm: reboot Tainted: P ---------------- 2.6.32 #1 empty RIP: 0010:[<ffffffff81305c2b>] [<ffffffff81305c2b>] free_msi_irqs+0x11b/0x130 RSP: 0018:ffff880185c9bc88 EFLAGS: 00010282 RAX: ffff880219f58bc0 RBX: ffff88021ac53b00 RCX: 0000000000000000 RDX: 0000000000000001 RSI: 0000000000000246 RDI: 000000000000004a RBP: ffff880185c9bcc8 R08: 0000000000000002 R09: 0000000000000106 R10: 0000000000000000 R11: 0000000000000006 R12: ffff88021e524778 R13: 0000000000000001 R14: ffff88021e524000 R15: 0000000000000000 FS: 00007f90821b7700(0000) GS:ffff880028220000(0000) knlGS:0000000000000000 CS: 0010 DS: 0000 ES: 0000 CR0: 000000008005003b CR2: 00007f90818bd010 CR3: 0000000132c64000 CR4: 00000000000006e0 DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000 DR3: 0000000000000000 DR6: 00000000ffff0ff0 DR7: 0000000000000400 Process reboot (pid: 5910, threadinfo ffff880185c9a000, task ffff88021bf04a80) Stack: ffff880185c9bc98 000000018130529d ffff880185c9bcc8 ffff88021e524000 <0> 0000000000000004 ffff88021948c700 0000000000000000 ffff880185c9bda7 <0> ffff880185c9bce8 ffffffff81305cbd ffff880185c9bce8 ffff88021948c700 Call Trace: [<ffffffff81305cbd>] pci_disable_msix+0x3d/0x50 [<ffffffffa00501d5>] ixgbe_reset_interrupt_capability+0x65/0x90 [ixgbe] [<ffffffffa00512f6>] ixgbe_clear_interrupt_scheme+0xb6/0xd0 [ixgbe] [<ffffffffa005330b>] __ixgbe_shutdown+0x5b/0x200 [ixgbe] [<ffffffffa00534ca>] ixgbe_shutdown+0x1a/0x60 [ixgbe] [<ffffffff812f6c7c>] pci_device_shutdown+0x2c/0x50 [<ffffffff813727fb>] device_shutdown+0x4b/0x160 [<ffffffff8107d98c>] kernel_restart_prepare+0x2c/0x40 ehci timer_action, mod_timer io_watchdog [<ffffffff8107d9e6>] kernel_restart+0x16/0x60 [<ffffffff8107dbfd>] sys_reboot+0x1ad/0x200 [<ffffffff811676cf>] ? __d_free+0x3f/0x60 [<ffffffff81167748>] ? d_free+0x58/0x60 [<ffffffff8116f7c0>] ? mntput_no_expire+0x30/0x100 [<ffffffff81152b11>] ? __fput+0x191/0x200 [<ffffffff816565fe>] ? do_page_fault+0x3e/0xa0 [<ffffffff8100b132>] system_call_fastpath+0x16/0x1b Code: 4c 89 ef e8 98 8c e3 ff 4d 39 f4 48 8b 43 10 75 cf 48 83 c4 18 5b 41 5c 41 5d 41 5e 41 5f c9 c3 49 8b 7d 20 e8 07 5a d3 ff eb c9 <0f> 0b 0f 1f 00 eb fb 66 66 66 66 66 2e 0f 1f 84 00 00 00 00 00 ehci timer_action, mod_timer io_watchdog RIP [<ffffffff81305c2b>] free_msi_irqs+0x11b/0x130 RSP <ffff880185c9bc88> ---[ end trace 27de882a0fe75593 ]--- (This was seen on a pretty old kernel/driver, but looks like the same bug is still possible.)

Jeff Kirsher says: ==================== This series contains updates to ixgbe only. v2- Dropped the following 2 patches from the series: ixgbe: Support using build_skb in the case that jumbo frames are disabled ixgbe: walk pci-e bus to find minimum width Ben Hutchings found a bug with Alex's patch, so that patch was dropped permanently. Jacob's "walk PCIe bus" patch is being re-worked for a more generic solution so that other drivers can benefit. In the remaining patches... Alex provides a fix where we were incorrectly checking the entire frag_off field when we only wanted the fragment offset. Alex also cleans up the check for PAGE_SIZE, since the default configuration allocates 32K for all buffers. Emil provides a change to the calculation of eerd so that it is consistent between the read and write functions by using | instead of +. Jacob adds support for displaying PCIe Gen3 link speed, which was previously missing from the ixgbe driver. He also provides a patch to clean up ixgbe_get_bus_info_generic to call some conversion functions, which are used also in another patch provided by Jacob. Jacob modifies the driver to enable certain devices (which have an internal switch) to read from the physical slot rather than reading data from the internal switch. Don provides a couple of fixes (which are more appropriate for net-next), one of which resolves an issue where ixgbe was only turning on the laser when the adapter was up which caused issues for those who wanted to access the MNG firmware while the port was in a down state. The other fix is for WoL when currently linked at 1G. Lastly Don bumps the driver version keep the in-kernel driver up to date with the current functionality. ==================== Signed-off-by:David S. Miller <davem@davemloft.net>

Host queues (Qdisc + NIC) can hold packets so long that TCP can eventually retransmit a packet before the first transmit even left the host. Its not clear right now if we could avoid this in the first place : - We could arm RTO timer not at the time we enqueue packets, but at the time we TX complete them (tcp_wfree()) - Cancel the sending of the new copy of the packet if prior one is still in queue. This patch adds instrumentation so that we can at least see how often this problem happens. TCPSpuriousRtxHostQueues SNMP counter is incremented every time we detect the fast clone is not yet freed in tcp_transmit_skb() Signed-off-by:

We reset during the shutdown path which will reset AUTOC register. This would change LMS to 10G. If we were currently linked at 1G we will lose link, which is a bad thing if we wanted WoL to work. For the fix I needed to know if WoL is supported so I created a new bool in the ixgbe_hw struct. If this is set we will not allow the reset to change the current LMS value in AUTOC. Signed-off-by:

We were only turning the laser on when the adapter was up. This causes issues for those who wanted to access the MNG FW while the port was in a down state. This patch makes sure the laser is turned on in probe and remain up even after the port is brought down. Signed-off-by:

This patch modifies the driver to enable certain devices, which have an internal switch, to read data from the physical slot rather than reading data from the internal switch. The internal switch will always report the same PCI width and speed, which is not useful compared to knowing the width and speed of the slot the physical card is plugged into. Signed-off-by:

The check for PAGE_SIZE is pointless now that the default configuration is to allocate 32K for all buffers. Since the Tx descriptor limit is 16K we can just drop the check and always compare the descriptors to the maximum size supported. Signed-off-by:

Patrick McHardy says: ==================== The following patchset adds support for running TIPC over InfiniBand. The patchset consists of three parts (+ a minor fix for the ethernet media type): - Preparation: removal of an the unused str2addr callback and move of the bcast_addr from struct tipc_media to struct tipc_bearer. This is necessary because InfiniBand doesn't have a fixed broadcast address like ethernet, so it needs to be initialized with the device's broadcast address when the bearer is enabled - Introduction of a TIPC InfiniBand media type. A new media type is needed to deal with the different address sizes - Support for ETH_P_TIPC in IPoIB Since the last posting I've addressed all feedback I received and rebased to the current net-next tree. I consider these patches ready for merging. Since they mainly affect TIPC code, I'd propose to have them either go through the TIPC tree or through Dave directly (not sure how TIPC patches are managed). ==================== Signed-off-by: -
Patrick McHardy authored
Support TIPC in the IPoIB driver. Since IPoIB now keeps track of its own neighbour entries and doesn't require the packet to have a dst_entry anymore, the only necessary changes are to: - not drop multicast TIPC packets because of the unknown ethernet type - handle unicast TIPC packets similar to IPv4/IPv6 unicast packets in ipoib_start_xmit(). An alternative would be to remove all ethertype limitations since they're not necessary anymore, all TIPC needs to know about is ARP and RARP since it wants to always perform "path find", even if a path is already known.

Add InfiniBand media type based on the ethernet media type. The only real difference is that in case of InfiniBand, we need the entire 20 bytes of space reserved for media addresses, so the TIPC media type ID is not explicitly stored in the packet payload.

Highlights include: * Properly exposing linux/openvswitch.h to userspace after the uapi changes. * Simplification of locking. It immediately makes things simpler to reason about and avoids holding RTNL mutex for longer than necessary. In the near future it will also enable tunnel registration and more fine-grained locking. * Miscellaneous cleanups and simplifications. ==================== Signed-off-by:
